Thanks Pete. done a bit more home work so getting the hang of the motor / prop thing I think. So how would I tell what's going to go faster? The 3200kv with 5s and say 4.7x4.7 or the 2350kv on 4s and 6x4? Is there any set formula or is it a after of experimenting?

and cheers nogas good to know. Pretty sure I'll run your setup as it seems pretty popular
on the crazier side anyone got near 300k/hr out of these? Any suggestions to get one there?
